ANTICREEPING DEVICE FOR RAILS- SPECIFICATION forming part of Letters Patent No. 793,100, dated June 27, 1905. Application filed July 20,1904. Serial No. 217369.

To ILIIJIIIL it 71m, concern.-

Be it known that I, FERDINAND SCI-IMETZ, a subject of the Emperor of (:ermany, and a resident of l'lerzogenrath, in the Kingdom of Prussia and Empire of Germany, have invented certain new and useful Improvements in An ticreeping Devices for R ails, of which the following is a specification.

My invention relates to railways, and has for its object to prevent the longitudinal travel or creeping of rails due to the recurrence of shocks at the joints.

The improved device hereinafter described is very simple, yet etlicient, and presents the further advantage of being applicable to existing tracks without any necessity for taking up the rails or otherwise disturbing them.

Reference is to be had to the accompanying drawings, in which Figure 1 is a cross-section on line 1 1 of Fig. 2. Fig. 2 is a longitudinal elevation with parts in central section. Fig. 3 shows a slightly-different form of wedge in cross-section. Fig. 4. is a plan of the wedge. Fi 5 is an end view thereof, and Fig. 6 is a crosssection showing another form of wedge.

My improved anticrcepcr comprises a clamp or shoe A, the ends of which are adapted to embrace the rail-base B. The ends A are curved to bear on the rail-base, and the body of the shoe upon its inner side has two converging inclines A A, rising toward the center, and two converging inclines A A", dipping to the center. The inclines A A are so directed (see dotted lines) as to be exactly or approximately tangential to the outer surfaces of the ends A. The opening between the said ends is wide enough to al low the shoe to be slipped laterally upon a rail without disturbing the latter. This insertion of the shoe is facilitated by the incline A era, (according as the shoe is put on from the left or the right,) which engages the bot tom surface of the rail-base and properly guides the shoe. After the shoe has been slipped on from one side far enough to have the end A clear the rail-base B at the other side the shoe is raised at said other side and slipped back to the position shown in Fig. 1.

In order to secure the shoe in position on the rail, I employ a wedge 0, having longitudinally-converging edges C, and preferably also provided with transversely-converging inclines C" C, forming the same angle with each other as the inclines A A and converging toward the same point as the edges C. These inclines U (1" may extend to the center of the wedge, so as to meet, as shown in Fig. 1, or they may terminate shortof the center, as indicated in Fig. 3. In any event the portions of the wedge engaging the shoe should not be sharp edges, but should be blunt or smooth, either by beveling them, as in Figs. 1 to 5, or by rounding them, as in Fig. 6. The wedge C may have a head C at one end, said end being adapted for engagement with a tie .l) or any other stationary part of the track or roadbed. It will be understood that the device is so placed on the track that the broad end of the wedge is in the direction toward which the .rail is liable to creep, said direction being indicated by the arrow (1/. Owing to the longitudinal and transverse incline of the surfaces A A, as in Figs. 1, :2, and 3, the shoe will be tightly wedged on the rail, and any shocks in the direction of the arrow a will only tighten the grip of the shoe, since the wedge cannot move in said direction. The dangerous creeping of the rails, the breaking of bolts and spikes at the joints, and the spreading apart of the rails are thus prevented, or at least guarded against, much more effectively than with the customary track construction. The new shoe is readily applied without disturbing the rails, and therefore without any interruption of the trallic.

Various modifications may be made without departing from the nature of my inven tion.

\Vhat I claim as new, and desire to secure by Letters Patent, is*

1. An anticreeping device for railway-rails,

comprising a shoe having bent ends for the reception of the edge portions of the rail-base, converging inclines arranged adjacent to said bent ends and rising toward the center, and converging inclines dipping toward the center, in combination with. a wedge arranged for insertion between the rail-basc and the dipping toward the center, in combination -with a wedge arranged for insertion between the rail-base and the shoe at the last-mentioned inclines of the shoe.

3. An anticreeping device for railway-rails, comprising a shoe having bent ends for the reception of the edge portions of the rail-base, and converging inclines dipping transversely toward the center, in combination with a wedge decreasing both in width and in effective height or thickness from one end toward the other and arranged for insertion between the rail-base and the said inclines of the shoe.

4. An anticreeping device for railway-rails, comprising a shoe having bent ends for the reception of the edge portions of the rail-base, and converging inclines dipping transversely toward the center, in combination with a wedge decreasing in width from one end to ward the other and having transversely and longitudinally inclined converging surfaces adapted forengagement with the shoe.

5. An anticreeping device for railwayrails, comprising a shoe having bent ends for the reception of the edge portions of the railbase, and converging lnchnes dipping transversely toward the center and also inclined lengthwise of the shoe, in combination with awedge decreasing both in width and in effective height or thickness from one end toward the other and arranged for insertion between the rail-base and the said inclines of the shoe.

6. An anticreeping device for railway-rails, comprising a shoe having bent ends for the reception of the edge portions of the rail-base, and converging inclines dipping transversely toward the center and also inclined lengthwise oi' the shoe, in combination with a wedge having converging surfaces inclined in accordance with those of the shoe.

7. An anticreeping device for railway-rails, comprising a shoe having bent ends for the reception of the edge portions of the rail-base, and converging inclines dipping transversely toward the center and also inclined lengthwise of the shoe, in combination with awedge engaging the said inclines of the shoe.

8. An anticreeping device for railway-rails, comprising a shoe having bent ends for the reception of the edge portions of the railbase, and converging inclines dipping transversely toward the center and also inclined lengthwise of the shoe, in combination with a wedge having blunt or smooth portions engaging said inclines of the shoe.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
